GAS-BURNER.

To all whom it may concern Be it known that l, GEORGE a citizen of theUnited States, residing in l the city and county of Philadelphia, Stateof Pennsylvanimhave invented a new and useful Gas-Burner, of which thefollowing is a specification.

My invention consists of an improved as burner comprisingy'a pluralityof para lel perforated tubes having means for regulating the gas and airsupply.

It further consists of such a burner'provided with a pilot light andwith means for preventing air-draft between the tubes from blowing outsuch pilot light. lit further consists of other novel features ofconstruction all as will be hereinafter fully set forth.

The annexed drawings and the following.

description set forth in detail one mechanical form embodying theinvention, such de tail construction being but one of various mechanicalforms in which the principle of the invention may be used.

In said annexed drawings Figure 1 represents a perspective view of my.improved gas-burner. Fig. 2 represents a top plan View of the burnerwith parts in horizontal section and broken away. Fig. 3 represents alongitudinal section through one of the burner tubes.

Similar numerals of reference indicate corresponding parts in thefigure.

Referring to the drawings, the reference numeral 1 indicates aconnection having a nipple, 2, or similar attaching means to the andformed witha'seat, 3, for of the usual or any preferred form. Theconnection is secured upon the upper side of a, chamber, 5, formed withjetn'ipples, 6, in its inner wall. This chamber, which may be termed amanifold chamber, is illustrated as having two nipples, and has a flatinner wall, 20-, from which-projects a screw-threaded stud, 7.Regulating valves, 8, formed by screws having fiatinner ends, darethreaded through the outer wall of the manifold chamber and havelock-nuts,

tubes, 11, have webs, 12 and 13, at their inner and outer ends toconnect them. The inner web has a screw-threaded opening which screwsupon the threaded stud of the chamber to secure the tubes .to the samewith their inner ends a distance from the wall of Specification ofLetters l atent.

the chamber and axially registering with the .jet-nipples. I outerportions of the burner-tubes have jetopenings, 14, for the inflammablemixture formed in the tubes. A sleeve, 15, is slidable upon the inner,imperforate portions of the tubes to more or less close the spacebetween the latter and the chamber. Said sleeve is formed with alongitudinal slot, 16, through which passes a screw, 17, into one of .te tubes to limit the longitudinal play of the sleeve. A pilotburner-tube, 18, extends- -from the connection and over the dampersleeveto the perforated portions of the burner-tubes, and a plate, 19, issecured be 'neath the end of the pilot tube and between the burner-tubesto protect the pilot-flame against draft coming up through the spacebetween said tubes and liable to blow out such flame.

The gas-supply can be regulated by the screw-valves, and the air-supplyby sliding the sleeve, which can be secured in its adjusted position bymeans of the screw. The

pilot-jet will always burn, ready to light the jets of the burners.

Other modes of applying the principle of my invention may be employedfor the mode herein explained. Change may therefore be made as regardsthe mechanism thus disclosed, provided the principles of constructionset forth respectively, in the following claims are employed.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. A. gas-burner, comprising .a chamber having a gas inlet and ajetnipple in one wall of the same, a burner tube arranged to registerwith saidnipple and at a distance from said wall and formed withjetopenings in its outer portion, and an aircontrolling sleevelongitudinally slidable upon'the imperforate inner portion of said tubeto more or less cover the space between the inner end of the tube andthe chamber and to be covered by the latter when in its extreme closingposition.
